How to Start a Business in Massachusetts
Everything it takes to legally start a business in Massachusetts, in order — with the official Massachusetts links for each step. Most people can complete the core setup in one to three weeks.
Pick a structure (sole proprietor or LLC)
Most Massachusetts owners start as a sole proprietor (free, no filing) or form an LLC for liability protection. The LLC filing fee is about $500, and formation typically takes about 1–2 business days online. Confirm the current fee on the state site before you pay.
Name a registered agent
If you form an LLC or corporation, Massachusetts needs a registered agent with a physical in-state address. You can be your own agent if you're available during business hours, or hire a service for about $100–$150/year.
Get your EIN from the IRS
An Employer Identification Number is free from the IRS and takes a few minutes online. You need it to open a business bank account and to hire.
Register for Massachusetts taxes
Massachusetts has a state sales/use tax and has a state income tax. Massachusetts is expensive for LLCs — $500 to form and $500 every year for the annual report.
Confirm local licenses and permits
Massachusetts rarely issues a single statewide "business license" — most licensing is by city or county, plus profession-specific licenses. Check your city and your trade.
Open a business bank account and get insurance
Keep business and personal money separate from day one. General liability insurance is the baseline; some contracts also require a bond.
Put the ongoing report on your calendar
Massachusetts requires a annual report (about $500).
